Subject: configs/debug: set CONFIG_DEBUG_INFO=y properly
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d1eff16d727ff257b706d32114d3881f67cc9c75;p=linux.git

configs/debug: set CONFIG_DEBUG_INFO=y properly

CONFIG_DEBUG_INFO can't be set by user directly, so set
CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y instead.

Otherwise, we end up with no debuginfo in vmlinux which is a big no-no
for kernel debugging.
